To this l add gradually solution OF per
manganate of potssss-eight grains t.
one ounce of water-by the O her neck o.
the bottle, and then cork that neck. A.
the fluids commingle, oxygen gas anC
ether vapor are given of freely, and csI

The sewerage of London, amounting to
nearly 200, 900, 900 gallons dsy,is carried
by the great sewers twelve miles to huge

one grain per gallon of sodium manganate
and few grains of chloride of lime.
After precipitation of the solid matter,
the effuent is discharged into the river at
